IMPROVEMENT IN ou'MPme-cARsl Specification forming part of LettersPatent No. 138,361, dated April 29, 1873; application filed March 17,1873.

To all whom it may concern:

Be it known that I, OWEN M. AVERY, of Pensacola, in the county ofEscambia, and State of Florida, have invented a new and Improved(Jar-Dumper; and I do hereby declare the following to be a full, clear,and exact description of the same, reference being had to theaccompanying drawing forming a part of this specification, in which-Figure 1 is a side elevation. Fig. 2 is an end view with parts brokenout, and Figs. 3, 4, and 5 are detail views of the coupling.

The invention consists in dumping a car on the side by means ofrockingbeams pivoted to the middle of a beveled bolster. It alsoconsists in a peculiarly constructed and operated shifter by which therock-beam is made to perform its intended function. It also consists ina locking device applied at each end of the shifter. It also consists ina doublenotched lock-bar applied to the middle of shifter. It alsoconsists of the means, hereinafter described, for throwing the line ofgravity from the median line of truck and to that side of car on whichthe load is to be dumped. These features of invention will all be firstdescribed in connection with whatever is necessary to their fullunderstanding, and then pointed out more distinctly in the claims.

In the drawing, A represents the wheels of a dumping-car truck journaledin the sideplates B B, which also receive the intermedi-' atetransom-beam O. D is a stationary bolster beveled downwardly each Wayfrom the center, and E is a rocker-beam. Through both of these, as wellas through the bumper F, passes the king-bolt 6 having the rounded head0 This allows the rocker-beam to turn vertically or horizontally. G is asemicircular piece or shifter, whose ends 9 gpass up through apertures cc in the transom-beam G. On the lower side, or about the middle of thesemi-' circle, is a loop, 9 by which the piece G may be moved. Each endof the piece Gis perfo rated, fits between a pair of perforated lugs, ee and receives a pivot-pin, 6 By this arrangement, as the shifter G ismoved by a bar, H, in one direction, the opposite end of rocker-beam isbrought down, and the loadthen dumped on that side. The shifter G hasnear each end a shoulder or catch, g which rests upon the latch I, thatmay be either made to slide in and out or made removable, and at tachedby a cord to transom -beam, 0. This latch is slipped out just before thecar is to be dumped. The bar H is provided with two rectangular notches,h h, one of which fits over the loop 9 of shifter, and the other over aloop, I), attached to the under side of plates B B. This produces asecond middle or supplementary locking device, by which the shifter ismade to hold the bolster rigidly in a horizontal position. In each endof bar H is a cross-pin, h which prevents the said end from passingthrough loop 9 and the bar from falling under the truck. The transombeam0 is made to project and given an oval shape 0 so that a cam -shapedlever, .I, with bifurcated end may be applied over the crosspin of bar11 and against the oval 0 This enables the center of gravity of the loadto be thrown out of the middle of car-truck, and over to that side onwhich the dumping is intended to take place. KK represents theconnecting-bars, each perforated at several points and adjustable on theother through the bolsters. One end of each is beveled on the outeredge, and held by sliding bandsL L and pins or bolts M M to the body ofthe other, while each outer end is provided with a bumper, is, link 20and latch 70", of the novel construction shown in figures of thedrawing. This forms a very simple and convenient coupling device.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. The stationary bolster D beveled downwardly from middle to each end,and the rocker E pivoted to the middle of said bolster, combined andarranged in connection with a car-dumper, as and for the purposedecribed.

2. The combination with a stationary rocker-beam, D, and a movable beam,E, pivoted together over the middle of the curved shifter Gr, arrangedand applied as and for the purpose described.

3. The latch I, combined with the shoulders crosspins at the ends of thecam-shaped g on shifter G to flock the latter, in the lever J, and beamhaving oval shaped end 0 manner described. as and for the purposedescribed.

4. The bar H having rectangular notches OWEN M. AVERY. h h, combinedwith loop 9 0f shifter and loop Witnesses: b of plate B, as and forthepurpose set forth. A. E. G. AVERY,
